dc.description.abstract | An ultrasound transducer is a critical and important component of any ultrasonic measurement system. Transducers convert electrical energy into acoustic energy and vice versa to transmit and receive sound waves.
The study in this thesis mainly focuses on the simulation of single element piezocomposite ultrasound transducers by using the Lithium Niobate (LiNbO3) as a main material for piezocomposite and different polymer fillers such as hard, soft material and air. We compared the two different cuts of composite such as 36֯ / Y-cut and Z-cut.
The transducer was designed in COMSOL (Develop FEM simulation models in COMSOL Multiphysics(2D) in both 36֯ / Y-cut and Z-cut).
3MHz of the 36֯ / Y-cut LiNbO3 sample was measured in the USN laboratory. | |
